OPHTHALMIC MOUNTING.

Application filed voctober 29, 192A.V Serial N. 746,549.-

' To all whom t may concern Be it known that I, IVILLIANI H.'BoU'rnr.Ln, a citizen of the United States, residing at Sturbridge, in the county of Vorcester and State of ltassachusetts, have invented' oertain newV and useful Improvements in Gphthalmic lvIountings, of which the following is a specitication. .Y

This invent-ion relates to improvements in ophthalmic mountings and has particular reference to an .improved compositemounting, that is, vone ciomprisingboth metallic and nonmetallic parts, and to the provision of an improved method of producing the same. y

in important object ofthe invention is .to provide an improved ophthalmic mounting wherein a metallicinember is provided with` a non'metallic covering.

Another object is to provide such a covering which will be securely held in place b v an interlocking member without the use of extraneous metal fastening means. i

Another object to provide .an improved method of producing such a mounting whereby the same may be practiced commercially in apracti'cal manner.

lith these and other objects in view, the invention resides in novel features of construction, combination and arrangement'of parts hereinafter isetforth, illustrated in the accoml'ianying drawings and particularly pointed out in the appended claims. y

In the accompanying .drawings forming part of this specification and wherein similar reference characters are used to designate corresponding parts throughout the several views:

Figure 1 is a front elevation of a complete spectacle, having endpieces embodying the invention.

Figure 2 is a detail perspective view of the endpiece and its connecting parts.

Figure 8 is a vertical sectional view on the line 3 3 of Figure 2.

Figure 4 is a vertical sectional view on the line 4 4 of Figure 2.Y

Figure 5 is a detail perspective view of one of the endpiece members.

Figure 6 is a top plan view of the metal endpiece without its nonmetallic cover.

Figure Tis a sectional view showing the application of the invention to the construction of a temple.

rIhe spectacle illustrated in F igure 1 comprises the usual pair of lens receiving rims 10 connected by a bridge member 11 and provided at their opposite sidespwith endpieces generally designated by the reference character 12 to which are'secured a pair of temples 13 of any ordinary or desired construction. As best shown in Figure 2, the lens receiving-.rims are formed bythe combination of an inner metallic rim 14 and an outer nonmetallic rim 15, both of which are fastened together as by interlockingA the ends 16 of the outer member over the inner rim 14. The outer rim may be formed of any suitable non'metallic vmaterial such as zylonite or other cellulose composition ma-l terial and the covering of the temple 13 is also formed of asimilar material. I i

The lens rims 10 are preferably split and the endpieces 12 are secured to the meeting ends 'of the rims as is usual. Theonter portion ofthe endpieces is rearwardly disposed as illustrated at 17 in Figure 6 and the opposite faces of the endpieces are recessed so as to form a temple receiving groove 18 in which is positioned a pivoting post 19`of the usual type. rIhe forward extremity 20 of the temple 13 is provided with an aperture 2l by` which it is pivotally mounted upon the post 19, and the parts are securely held in place by a clamping screw 22 ydisposed in the endpiece members.

In o-rder that the endpieces may harmonize with the lens rims 10 in appearance, I provide a pair of nonmetallic cup shaped members 23 formed to completely cover the endpiece members 12. Y

In order to facilitate fastening of the covering shells 28 to the endpiece members 12, I provide said endpiece members with a notch or recess 24 into which I introduce a nonm'etallic plug member 25 which is, at its outer surface 26, flush with the edge of the endpiece member. In this way I can cement the inner surface of the shell 23 to the outer surface of the plug since both members are made of the same vkind of material that will become firmly united. In view of the fact that the notch or recess 24 is hand cut there will be no possibility of the plug member becoming accidentally displaced.

In Figure 7, I have illustrated the application of my improved structure to the construction of a temple wherein the extremity 2O of the temple` issuitably notched or recessed as at 27 for the reception of a nonmetallic insert 28. The covering 13y of-the temple is so formed that it may be extended over the edgeof the extremity 20so as to overlie theinsert 28 to Which the nonmetallic covering 13 is secured as by cementing.

In use, the endpiece covering 23 Willnot interfere in any Way With the separation of the endpiece members .12,either' for the insertion of lenses in the lens rim 10 or for the changing of #the temple. Furthermore it Will be apparent rthatfthere is no possibility for said non-metallic'endpiece covering becoming loose, sov that the metal endpieces Will' be entirely concealed and then-:coverings Will harmonize -With the outer rim member 15.

lFrom the -foregoing it Will-be apparent that I'have produced an improved ophthalmicV mounting', comprisingV metallic `and nonmetall'ic parts secured together' in a simple but reliable manner. Obviously, changes maybe resorted to inthe minor details of construction andv arrangement of parts, and the right -is fherein' reserved to -make such changes falling Within the scope of the appended claims Without departing from the spirit of my invention.

VHaving thus described my invention, what isA claimed is:

' 1. An ophthalmic mounting comprising a. met-allic- `memberprovided in one of' its sur faces With'a-recess, a nonmetallic plug'` secured in therecess, and a nomnetallic covering on a surface of the metallic member Aand secured to `the plug.

2. An ophthalmicmounting comprising a metallic memberprovided in one of its surfaces with an undercutrecess, a nonmetallic plug securedinl the recess, and a nonmetallic covering Vsecured tothe outer surfaceof the plug and extending overthe surface of the metallic member.

8. An ophthalmicmounting comprising la 4 split lens receiving'rim, endpieces carried by the meeting ends of `the rim, each of said endpieces being notched, nonmetallic plugs disposed inthe notches, andv a nonmetallic shell covering theiendpieces andfseoured to -the plugs.

-endpieces and-fastened to the outer surface of the inserts.

5. An endpiece comprising a -metallio body portion having -arecess-in onel of its surfaces, `a nonmetallic insert disposed in the recess, l'and a nonmetallic covering on vthe' body portion, said covering being cemented tothe outer surface of the insert.

6. The'method ofzproducing a composite ophthalmic mounting consisting informing a metal boldy vmember* of thev desired shape, providinga-'recess in oneedge offthe body member, inserting a `nonmetall-ic member Withinthe recessivith its outer surface flush with lthe edge of 4the body -member, forming a covering ofnonmetallic materialv'for the recessed edgeof the body member, andrsecuring said coif'ering toi-the inserted-neumotallic lmember.

7. The-method ofaproducing a composite ophthalmic mounting consisting informing a metal body member of the desired-shape, providing al1-undercut groove 4i-neone edge thereof, inserting a nonmet-al'lic filler in-the groove Withits outer surface flushwith the edge of thebody member, ,formi-nga covering of,nonmetalliemate-rialfor the groo-ved edge of the body member, and cementi'ng said covering to Athe outer surf-ace of the nonmetallic filler.

-8. The-method of producing a composite ophthalmic mounting consisting in. forming a metalbody member ofthegdesired shape,A

providing-an undercut groove inione `edi-ge thereof, inserting axnon'metfallic filler ,in the groove, forming uathin nonmetallic shellnas a `covering for 'the metalbody member, and

securing said shell to the nonmetallic filler.
